Wind Energy

Wind turbines use the momentum of moving air to quietly turn large blades that are attached to the shaft of an efficient electric generator.

Wind energy is a major contributor to Green Power Switch. TVA has one wind power site, located on Buffalo Mountain near Oak Ridge, Tenn. The site has 15 very large and three smaller turbines.

How large are the blades on the wind turbines? See the Wind Q&A for the answer to this question and others.

Biogas

Wastewater methane collection is a potential source of renewable energy. Biogas energy is produced when organic wastes decay – in wastewater treatment plants or landfills, for example. TVA collects methane gas, a by-product of organic decay, from the city of Memphis wastewater treatment plant and co-fires it with coal at Allen Fossil Plant.

How does firing methane with coal help the environment? Read the answer to this and other questions in the Biogas FAQ.
